RETORT FOR AMMONIA ICE-MAKING APPARATUS.

SPECIFICATION forming-part; of Letters Patent No. 298,669, dated May 13, 1884:.

Application filed August 10, 1883. (No model.)

To all whom it may concern.-

Be it known that I, MAHLON S. OoNLY, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Retorts for Ammonia Ice-Making Apparatus, of which the following is a specification.

The general process of forming ice by the use of ammonia, and which consists, essentially, in producing in a retort ammoniagas from liquid ammonia, or ammonia and water, passing the same through a cooler and thereby condensing it, then passing it through a series of large pipes in the refrigerator, where it expands and absorbs heat, and finally passing it into an absorber, where it is taken up by water and put in condition to be again passed into the retort and through the same process, is no part of my present invention, and will not be further described herein.

My present invention relates to the con struction and method of using that portion of the apparatus known as the retort; and it consists in an arrangement of tubes and partitions whereby the aquaammonia is subjected to a constantly-increasing heat from hot water, which passes through tubes in said retort and around the outside of it, the aqua-ammonia' at the same time passing in the opposite direction through the retort around the partitions therein, as will be presently more fully described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a side elevation of a complete apparatus for producing ice, of which my improved retort forms a part; Fig. 2, a horizontal sectional view on the dotted line :4 a; Fig. 3, a longitudinal vertical sectional view, looking to the left from the dotted line 3 y,- and Figs 4, 5, and 6, transverse vertical sectional views, looking to the right from the dotted lines m w, w w, and o '0, respectively.

In said drawings, the portions marked A represent the shell of the retort; B, a casing surrounding the same; 0, the hot-water inlet; D, the hot-water outlet; E, the aqua-amnionia-inlet pipe; F, the ammonia-gas outlet; G,

the weak-aqua-ammonia outlet; H, the condenser for the ammonia-gas; I, the liquid-gas reservoir; J, the cooler for the weak aqua-ammonia; K, a pipe leading from the liquid-gas reservoir to the refrigerator; L, said refrigerator; M, a pipe leading from the refrigera- 5 5 tor to the absorber; N, a pipe leading from the cooler J to the absorber; 0, said absorber;

P, a pipe leading from saidabsorber to a forcepump; Q, said force-pump, which draws the aqua-ammonia from the absorber through pipe I, and forces it to the retort through pipe E; and R, a circulation-pump attached to the refrigerator by pipes R R", which is for the sole purpose of keeping the salt-water therein in circulation.

As hereinbefore stated, my present invention relates to the retort only, and the other portions will not therefore be further described herein. g

The shell A is constructed much as a steam- 7o boiler is constructed, with the pipe-fiuesa extending from end to end thereof. It has also two partitions, a of, one of which extends from one end to near the other end, and the other of which extends from the last-mentioned end back to near the first. Said partitions are so arranged as to divide the tubes a into groups. The casing B surrounds the shell A from the bottom to near the top, leaving a spacebetween the outside of said shell and the inside of said casing. This space is divided into two C0111- partments by a longitudinal partition, I). The spaces between the ends of the shell A and" casing B are each divided into two unequal spaces by partitions 1) b which are practi- 8 5 oally continuations of the partitions a a Into the smaller of these spaces, at each end, three of the pipes to open, and into the larger of said spaces six of said pipes. Into one of these smaller spaces the hot-water-inlet pipe O enters, and the hot water which flows in through this pipe passes on through the pipes and out into the space b between the shell A and easing B, on the corresponding side of the partition I). The hot water then flows out into the larger space at the opposite end, and back through the middle group of pipes, to the larger space at the first end. From this space the water passes through the final group of tending through from end to end, and parpipes and the space 19* to the overflow-pipe D, and passes off. The strong aqua-ammonia is forced through the pipe E into-the shell A, at the opposite end of the retort from that at which the hot water enters, and enters the left-hand compartment of said shell, (see especially Fig. 4,) surrounding the group of pipes in said compartment, and flowing to the opposite end of the shell, in contact with said pipes, where it passes around theend of the partition a, into the middle compartment, and thence back to the end at which it entered, and around the end of the partition a", into the right-hand compartment, and finally, after passing through said compartment, that portion that has not been generatedinto gas passes outthrough the pipe G into the cooler I, having become by this time a weak ammonia-liquor, most of the ammonia having been generated into gas and passed off up the pipe F into the condenser E.

By tracing the course of the hot water and that of the ammonia-liquor,as above described, it will be seen that the entrance and exit of each is at the opposite point in the retort from the shell of the retort and the pipes passing through the same.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an ice machine or apparatus, a retort consisting of a shell having tubes or pipes eX- titions alternately extending from one end to near the other, in combination with the hotwater, aqua-ammonia, and gas pipes, substantially as set forth.

2. In a retort for generating ammonia-gas,

a series of pipes and partitions whereby the aquaammonia is caused to flow in one'direction through the retort, and the hot water is caused to flow in the other direction, thussubjecting the aqua-ammonia to a constantly-increasing heat, substantially as set forth.

3. In a retort for generating ammonia-gas, a series of pipes connecting with a hot-water inlet at one end, and arranged to secure several passages of the water through the retort before passing out at the other, and a series of partitions forming compartments connected i es a and artitions a a the casing B sur-- rounding the shell A, and having the spaces between itself and said shell divided into compartrnents by partitions, a hot-water inflowpipe, 0, a hot-water outflow, D, an aquaammonia inflow, E, an ammoniagas outflow, F,-

and a weak-ammonia-liquor outflow, G, said several parts being arranged and operating. substantially as shown and specified.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 4th day of August, A. D. 1883.
